2008 CRF70 Muffler Bolt Size?

Recommended Posts

Anyone happen to know the size of the bolt that attaches the muffler to the frame? My son's 2008 CRF70 has a Two Brother pipe on it but last weekend the bolt that holds the muffler on came loose and fell out. I need to replace it so we can ride tomorrow and thought it would be much easier if I knew what size to buy before I go trying to find one.

Just a thoguht .. :thumbsup:

If the bolt becomes loose on a regular basis ? Try gett'n a longer bolt and adding a nut on the other side of the frame .., this incase the threads in the frame are worn out and the bolt doesn't stay tight ..

Good idea, just bought the bike a couple months ago and first time the bolt came out. Bike came with the pipe on it so I wasn't for sure what size it was and have been out of town all week. Adding a nut couldn't hurt, good idea.
